City of Austin Resilience Hub Planning
Background
The general goal of the COA resilience hubs are neighborhood sites for disasters that provide the necessary power and water redundancies, shelter, heating, cooling, and refrigerated storage and walkable within 15 minutes for every Austin resident. The sites will be existing physical spaces (e.g., recreation centers, schools, churches, nonprofit spaces) and important social spaces where people can congregate, exchange information and will help residents prepare for climate impacts, respond when an event occurs, and help neighborhoods recover after an event has occurred. These goals align with the general policy discourse on resilience hubs as community-serving facilities augmented to support residents and coordinate resource distribution and services before, during, and and/or after a natural hazard event.
COA Planning Meetings and Participants
The City of Austin has convened meetings to plan for the implementation of the COA Resilience Hubs. In total, 34 meetings/events have occurred between January and May 2022. The data for the analysis below is generated from the participant list at each of the planning meetings. A total of 103 different individuals have attended at least 1 meeting.
Methods
We can better understand how the participants interact over the course of these meetings by creating a participant-meeting matrix. We can move from this participant-meeting matrix (in network terms this is considered a bi-partite netowrk) and create a participant-participant list by multiplying the matrix (M) by the transpose of the matrix (T). MxT = a participant-participant list.
Building a network from an adjacency matrix
From the adjacency matrix we can build a graph object using igraph in R. This graph object can be displayed as a network. Therefore, the stakeholder attendance at planning meetings forms the basis for network analysis, with the co-attendance of two individuals at the same meeting defining an interaction of those two individuals.
Network clusters
We can start to see how certain individuals interact more with each other than others by seeing patterns of participation at different meetings. We call this network modularity and we can visualize different subgroups that exist in this network of participants. In particular, we see four major sub-groups in the network of participants.
Interactive Network Visual
Using the network information, we can map the network in a interactive format. In the map below, each square represents an individual and connected squares mean that they participated together in at least one meeting. The larger the square the more other individuals that person has attended meetings with from Jan. to March.
Geospatial plotting of participants
The participants in the network map above all come from somewhere across the city. The map below plots each meeting participant across the Austin area.
Network centrality
One of the tools frequently used by network analysis is understanding who is “most central” in the network. The table below lists all participants (by their affiliation) and is ordered in descending “degree centrality”. Degree centrality has been associated with both activity as well as influence in planning processes.
